Ryanair's social media team jokingly responded to an unwitting customer who complained about the service they'd received.
Over the past year the person or people behind the budget airline's Twitter channel has helped burnish the brand's reputation with brutal quips.
In the past, it has joined in with jokes about the way the airline seems to charge for almost everything and the amount of legroom available for each seat.
This month a Twitter user called Paul found the spotlight land on him after he posted about the company's check-in policy.
"Another reason not to fly @Ryanair," he wrote.
"If you don’t pay for pre-booked seats you can only check-in max 24 hours before your departure, meaning you need to check-in for your return while away, most likely forgetting and then costing €55 to do it at the airport if less than two hours before flight."
In response Ryanair posted a picture of phone screen with a 'reminder' option and the words: "adulting is hard".
People's reactions were divided - some found it funny, but others were unimpressed.
One person fumed: “The Ryanair Twitter account is clearly being run by a college student, or, a college student in grown up clothes.
“This stuff isn't even witty anymore, just a bit pathetic frankly. Instead of using light criticism of the product as an opportunity to improve, you resort to this.”
However, others agreed with the airline’s joke.
One user commented: "I'm seriously wondering how people survive if they can't even manage the tiniest tasks. It takes less than a minute to check-in for a Ryanair flight when you're using the app.”
As much as everyone can enjoy the social media team's devil may care attitude towards customers service, anyone who has been caught out by Paul knows his pain.
Unlike other airlines, everyone flying with Ryanair needs to check-in online before they get to the airport.
If they fail to do so and their flight departs in less than two hours, then Ryanair charges an extra £55 fee, or £30 for flights from Spain.
If you have checked in but you have not printed your boarding pass, you will be charged for the boarding pass reissue fee, which is £20 per passenger.

For Ryanair online check-in opens 60 days before the scheduled departure time if you have purchased an allocated seat.
Customers can be allocated a seat free of charge if they check-in online between 24 and two hours before each booked flight.
Once you have checked in online you can print copies of your boarding pass, or download them to your mobile phone, up to two hours before the scheduled departure time.
Your boarding pass must be printed on a single A4 page or downloaded through the Ryanair app. If not you could face a fine.
Ryanair does operate airport check-in but charges apply.
It's also important to note some airports do not accept Ryanair's mobile boarding passes. These are:
- Kefalonia
- Turkey
- Morocco
- Israel
- Lebanon
Customers traveling from these airports must check in online and print out a paper boarding pass for their flights.
It's also worth keeping an eye on hand luggage allowance.
Ryanair lets passengers bring one small personal bag onboard for free, such as a handbag, backpack or laptop bag, measuring no more than 40x20x25cm.
If you want to bring a second bag, you can pay to add 'Priority & 2 Cabin bags' to your booking. This allows you to bring your small personal bag, as well as a 10kg wheelie bag measuring no more than 55x40x20cm. Alternatively you can also pay to add a 10kg check-in bag option to your booking.
